Cryostasis is a multi-purpose card heavily designed for Freeze Shaman decks. It can be utilized as a cheap buff effect on friendly minions, or it can be used for it's Freeze effect, allowing it to activate cards such as Moorabi and Ice Breaker.

0-Attack minions can take advantage of this card due to how Freeze works. Freeze causes the affected character to skip the next turn they can attack on, so this card causes the 0-Attack minion to skip the turn when it received this card's stat buff, and will become un-frozen at the end of the turn, allowing it to attack on the next turn.

In Arena, Cryostasis can be a reasonable choice. In a lot of situations, it can be used for it's buff effect, as it's difficult to draft enough Freeze synergy to utilize that effect positively, and the buff can be used on a Taunt minion to make it more awkward to remove, or make a high-value minion with an active effect more difficult to deal with efficiently.
